Hello newsgroup, I hope that there is so out there who can help me, because I simply don't know where to look at. We're using OTRS since several years and I'm really enthusiatic for it, but since the update from version 2.2.7 to 2.3.2, there is a strange error in customer.pl. When a customer tries to logon, he receives the following statement and nothing further happens: Software error: No MainObject! at /opt/otrs//Kernel/System/AuthSession.pm line 83. We're using three backends for customers, the normal otrs-database, one ldap against ActiveDirectory Win2k3 and one "external" MySQL-DB. We're authenticating customers against ldap OR otrs-DB, thanks to Ralf Becker's Multiple.pm. Everything worked fine under OTRS 2.2.7, but now our customers get this strange message when they try to login. The authentication seems to work fine corresponding to the SystemLog, also for ldap as for DB-Users, so where could the error belong to? I'd appreciate every little hint. Thanks in advance Markus Nagel PS: Forgot the System environment: Suse Linux 9.0 MySQL 4.0.15 Perl 5.8.1
